IMPROVEMENT IN PRINTING-PRESSES.

Specification forming part of Letters Patent No. 118,182, dated August22, 1871 antedatcd August 18, 1871.

To all whom it may concern:

Be it known that I, WrLLrAM L. BALcH, of Boston, in the county ofSuffolk and State or' Massachusetts, have invented a neuT and ImprovedPrinting-Press, of which the following description, taken in connectionwith the accompanying drawing, hereinafter referred to, forms a full andexact specifica-tion, wherein I have set forth the nature and principlesof my said iinprovements, by. which my invention may be distinguishedfrom all others of a similar class, together with such part-s as I claimand desire to have secured to me by Letters Patent.

The present invention relates to a press for printing cards and papersheets, and designed princil'xally for the use of amateur printers; theobject of the invention being to accomplish the inkin g of the types andthe printing of the sheet in a simpler and more complete `manner than isdone by any press of a similar class.

rIlhe accompanying drawing is a side elevation ot' my press, in which Arepresents the type-bed, which is inclined backward to prevent the typesfrom falling out of place; B, the platen, on which the sheet to beprinted is placed; U, the gripers, by which the sheet is held inposition while being printed; D, the inkingrollcr, and E the rotatingtable, on which the ink is spread.

The pressure necessary to effect the printing of the sheet is applied tothe frame of the platen B, at a point below and to the rear of itsturning point, by means ofthe compound lever F G, which is operated by ahandle or treadle, as may be desired, the handle-forni being shown in mydrawing. The inking of the type is accomplished by the passage oftheinkingroller over the ink table and then over the face ofthe form,motion being given to the frame H carrying the roller through the arm I,which so connects the frame H with the impression-lever F Gr as to causethe inking-roller D to pass over the face of the type at the propertime. The sheet is held firmly to the platen B While being printed bythe gripers C, whose action is controlled by the curved rod K passingthrough a socket, L, aiiixed to the frame oi the press, and bent to sucha form as to cause the gripers to grasp and relieve the sheet at theproper moment. Y

I claim as my invention- Actuating both the platen and the ink-rollerframe from lever M by means of links I G, coinbined substantially in themanner described.
